CLOSURE FASTEN Application filed April 15 1922. Serial No. 555 132.

To ZZ. whom it may 007266972-1 Be it known that I, JACOB Vl nnnn, acitizen of the Republic of Germany, and resi dent of New York, in thecounty of New York and State of New York, have invented certain new anduseful Improvements in Closure Fasteners, of which the following isspecification.

One of the principal objects of this. invention is to provide a bracketadapted to be attached to window frame and window sash to hold the sashadjustably secured in plurality of inclined ventilating positions.

Another object is to provide a bracket of this character which can bequickly and easily detached from the sash to allow the sash to be freelyraised and lowered in the usual manner whenever desirable.

A further object is to provide a bracket of this character with means toeffectually prevent the bracket from being detached from the-sash whenthe sash is in any of the inclined positions and a further object is toimprove upon the ar' devices with which I am familiar by simplifying theconstruction, whereby the devicemay be manufactured and sold at acomparatively low price. With these and such further objects in view aswill be apparent to those skilled in the art to which this apperta-ins,the invention consists in the construction, combination and arrangementof parts herein specifically described and illustrated in theaccompanying drawings, wherein is shown a preferred embodiment of theinvention but it is to be understood that changes, variations andmodifications may be resorted to which fall within the scope of theclaims hereunto appended.

In th drawings forming a portion of this specification Fig.1 is afragmentary side view of a window frame with my improved bracketattached thereto, the sash being shown in full lines in an inclinedventilating position.

Fig. 2 is a detail sid view showing the bracket in inoperative positionand detached from the sash.

Fig. 3 is a front view of the parts shown in Fig.2 showing the bracketattached to the sash, and

Fig. 4 is a detail perspective showing the sash fixture attached tothesash.

Fig. 5 is a perspective detail of the sliding head, and Fig. 6 is adetail.

Referring to the drawings 10 indicates sash 12 to be constructions ofsimigenerally the window frame in which the upper and lower sashes 11and 12 are mounted to slide in the slideways 13 and 14 respectively. Thelower section 15of the innor retaining strip of the slideway 14 ishinged as at 16 whereby it may be swung through an arc of 180 to allowthe lower moved to an inclined position as shown in full lines in Fig. 1of the drawings. A bracket 17 is suitably secured to the frame 10 andcarries at its lower end a headed pivot pin 18 which passes freelythrough suitable aperture in an'arm 19. The pin 18 is'preferably securedto the bracket 17 by riveting and carries between the arm 19 and thebracket 17 a pair of washers 20 between which is mounted a lock washer21. The lock washer 21 is placed under tension when the parts areassembled, thereby holding the arm upon its pivot with a firm butyielding frictional engagement.

The arm 19 is slotted longitudin'allyintermediate its ends as at 22 toprovide a guideway for the reduced end 23 of a sliding head 24 which isslotted as at 25 to provide a pair of yoke arms 24 between which thereduced end of a link 26 is pivotally secured as at 27.

Suitablemeans such as the screw 28'provided with a pair of washers 29and the lock washer 30 are provided to hold the gagement with the arm19.

The lower endof the link 26 is provided with a laterally extending hook31 which is adapted to engage within the aperture 32in the lug 33 whichprojects upwardly from a bracket 34 secured to the upper edge of thelower sash 12. A second lug 35 suitably spaced from the lug 33 alsoextends upwardly from the bracket 34 and is cut away as at 36 to providethe requisite clearance to allow the hook 31 to be engaged or disengagedfrom the aperture 32. It will be noted that the lug is cut away so as toform an arcuate face which terminates at its upper extremity in aprojecting shoulder 37 for a purpose which will hereinafter appear.

Referring to Fig. 1 of the drawing, the dotted line showing of the partsindicates the window sash 12 in closed position and from the relativepositions of the brackets 17 and 34 it will be seen that the adjustablearms 19 and 26 will occupy an inclined position when engaged with saidbrackets. When the sash is tilted from thevertical dotted head 24 infirm but vielding' frictional encomparatively slight movement of thewindew to theopen positionis-necessary to: lock the link; 26 within the.bracket.

It will thusbe seen that the window can not be opened from the outsideby any unauthorized person after it has been moi'ed t anopenventilating. position, In the assen 'bly of the parts. the lock washersare means; to. connect said link. and arm in placed under sufficienttension to hold the window. securely in any adfi sted position in whichit may be placed, without necessitating any" further tightening of any.bolts, nuts or. screws Likewise due to the presence of theloch washersthe parts. are held under a frictional spring tension which permitsthemtobe moiied by merely pulling the window to theg'desired positionwithout having. to exert anfundue amount of -force.

\ It will be noted that the reduced end 23 of thehead 2d is providedwith a projecting boss 4C0. which is internally threaded to. receiyeithescrew 28. The inner washer 29 and the lock washer. 30am. placed overthis boss and; it. will thus be seen that the transverse or. lateral;strain produced when the head flat is. slid lalongithe arm 19 is takenup by the boss i0- and. not by the screw 28.

Having thus. described; n y invention what I claim as new and desire tosecure by Let ters Patent of the United States is 1. In a closurefastener, a straight slotted arnn neans comprising a yielding frictionalconnection to pivotallyv secure. said arm to, a window frame, aconnecting linln yielding sliding frictional engagement and detachablemeans to pii'otaliy connect said arm to a window sash.

2 In a closure fastener, a straight slotted arm, nieans coinprising ayielding frictional connection to pivotally secure said arm to a windowtrams, a connecting link, yielding means to connect said link and arm intrictional engagement, detachable means to pivotally connect said arm toa window sash and means to prevent said means from being detached fromsaid sash when the sash is in an inclined position.

3. In a closure fastener means to secure the fastener to a window frame,a longitu dinally slotted straight arm, a head provided with a reducedend adapted to be received in the slot of said arm a threac'sed bossprojecting from said reduced end. a lock washer on said boss. and meansto engage said threaded boss to place said lock washer under tensionwhereby the head will be held in yielding frictional engagement withsaid arm.

at. In a closure fastener adapted to hold a window in, an inclined openposition, a straight arm having a longitudinal slot therein. a headprovided with a reducedend adapted to he received in said slot. athreaded boss projecting from said reduced end, a link pivotall; mountedon said head. a bracket adapted to be secured to the window sash,said-link and bracket provided with cooperating detachably engageablemembers, a lock washer on said boss and means to engage said threadedboss to place said lock washer under tension whereby the head will beheld: in yielding frictional engagement with said arrn.

Signed at New York in the county of New York and State of New York this17th day of November A. D. 1921.
